BURTON STEWART, OF ST. JOSEPH, MISSOURI.

METALLIC-CROWN WICK.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed October 25, 1916. Serial No. 127,683.

To all whom it may concern:

Be it known that I, BURTON STEWART, a citizen of the United States ofAmerica,

residing at 423 North Seventh street, St.

Joseph, in the county of Buchanan and State of Missouri, have inventedcertain new and useful Improvements in Metallic-Crown Wicks, of whichthe following is a specification. Y

The object of my invention is to provide a means for transformingkerosene oil into a vapor gas by manufacturing crowns composed ofperforated aluminum alloy to be attached on the top, burning ends ofkerosene oil stove and lamp wicks or to other mechanism or receptaclesin which a wick is used to conduct kerosene oil to a burner. Asaluminium alloy is indestructible so far as heat is concerned, by thenecessary constituencies of such a preparation applied to my inventionit is a positive gas generator.

1 accomplish my object by the means shown in the accompanying drawings,in which- Figure 1 is a partial view of an ordinary stove using keroseneoil, partly broken away, showing a wick in position;

Fig. 2 is a view, in perspective, of a stove wick with the aluminumcrown attached;

Fig. 3 is a partial view of a lamp, as ordinarily constructed, showing aperforated crown in position, and

Fig. 4 is a detail view of the fiat wick with a flat perforated crown.

Corresponding letters refer to corresponding parts throughout thedescription and in the drawings, the letter A representing any ordinaryportable kerosene stove having a circular wick holder A. B is a wicktherein of similar form. As shown in Figs. 1 and 2 the circular wick isprovided with a circular aluminum alloy crown O which clamps over thetop burner end D of the wick, that part of said crown on the inner sideof the wick being slotted vertically forming fingers E Ewhich hold thetop of the wick in rigid engagement 1 with the exterior of said crown C.The outer side of said crown is provided with horizontal slots F F.spaced apart, to permit the wick to be readilv and quickly ignited by amatchor other suitable means, and, as shown in Fig. 2, the entire crown,both on the outer side of the wick and the fingers E E. is closely per.

forated to feed the oil while the aluminum alloy protects the wickrendering it impervious to heat.

As shown in Figs. 3 and 4, said crown is readily'adapted to a fiat wickL for use with kerosene in lamps, thecrown being clamped over the topend of the wick on both sides in corresponding form to that shown on theone side of Fig. 4, the entire crown being 7 perforated, the wick inthis construction being readily lighted at the top ends indicated byletters 72, h in said Fig. 4.

It should be understood that in my device, both for use with stoves andlamps, the trimming of lamp wicks is practically unnecessary, therebysaving both labor and the expense of wicks, and, by the use of my metalcrowns on the top of the wicks the heat transforms the oil into vaporousgas, thereby eliminating all smoke and unpleasant odor and both lightingand heating power are largely increased. Moreover, int-he use of saidcrowns the danger of explosions by accidentally dropping a burning wickthrough a burner into the oil in a stove or lamp is wholly obviated.

What I claim and desire to secure by Letters Patent, is:

1. The combination with an oil stove and a circular wick therefor, of acircular perforated metallic crown seated on the top edge of said wicksaid crown being provided on the inner side'thereof with a plurality ofV shape fingers, spaced apart, to hold said wick in rigid engagementagainst the outer side of said crown, the outer side of said crown beingprovided with a plurality of horizontal slots, spaced apart, to permitsaid wick to be readily ignited.

2. Ina device of the land described, a perforated aluminum alloy crownseated on the top edge of a lamp wick, V shape fingers on theinner sideof said crown turned vertically downward to .hold the wick in rigidposition in the crown, and horizontal incuts, spaced apart, in the outerside of the crown to facilitate lighting of the'lamp.

In testimony whereof I aflix my signature in the presence of twowitnesses.

BURTON STEWART.
